Also, a power source part 9 supplies a power for driving each part, monitors the residual capacity of the power, and outputs the communication of the residual amounts.  The control part 5 receives the communication of the residual amount, and reads the prescribed voice signal data from the stylized voice storing part 7, and the voice signal data are converted by the voice synthesizing part 11. Thus, the decrease of the residual capacity of the power can be announced to a user by the voice signal.

Filed: 1987-11-18
Abstract: PURPOSE:To easily obtain an element structure having preferable characteristics by forming a superconductor electrode directly on the side face of a channel layer without the ion implantation for forming drain and source regions in a semiconductor. CONSTITUTION:A substrate 1, a non-doped layer 3 epitaxially grown on the substrate 1, and an N-type layer 4 are formed. A channel layer 7 formed of a two-dimensional electron gas layer is provided in the layer 3. A superconductor electrode 2 is formed through an insulating film 8 in contact with the layers 3, 4 on the N<+> type substrate 1. A gate electrode 6 and an insulating film 5 are formed in the structure of a semiconductor device. Since the electrode 2 is formed of a superconductor material, a region 9 which exhibits superconducting characteristic due to the proximity effect of a superconductor is formed on the region 7. Since carrier injection is performed through the region 9, the formation of drain and source regions by an ion implantation is eliminated. As a result, a lattice defect in a semiconductor generated at the time of ion implanting is avoided.

Abstract: PURPOSE:To display highly fine secondary image while an image display device is small and light by including an image-formation optical system for image- forming out of the light emitted by an emitter, and an angle adjustment mirror for adjusting the angle at a time when the light emitted by the emitter is incident on the eye of an observer. CONSTITUTION:The light emitted from an emitting means 14 passes an image- forming optical system 15, and is deflected by a deflection means 16, and after the light is reflected by an angle adjustment mirror 17, it reaches the position of an eye 18 of an observer. A filter 31 put between the deflection means 16 and the eye 18 of the observer, is provided on the opening of a case 30, and is made of a transparent material. By preferentially transmitting the wavelength of the light emitted by the emitting means 14, the light externally injected is reflected on the inside of an image formation device, and is cut before it reaches the eye 18 of an observer, along with the light that reproduces a secondary image, and a secondary image thus becomes clearer. A highly fine display can thus be achieved while the device is small.

Patent JP-H01133318-A (JP)
Title: Thin-film processing device
Inventor: KOMIYAMA KICHIZO
IPC: C23C14/50
Filed: 1987-11-18
Abstract: PURPOSE:To enable thin-film processing of large number of works under processing having a large diameter to be performed uniformly within each work being processed and between works being processed by rotating a holder mounted with a work to be processed on it axis and around its rotation axis and by moving the rotation axis in a reaction room by the rotation of a rotation body. CONSTITUTION:A holder 42 and a work to be processed 7 are heated by a heat source 3a. While a reaction room is kept to a prescribed degree of vacuum by exhausting air form an exhaust port 8, a reaction gas is introduced from a nozzle 9. A high-frequency voltage is applied to an electrode 3 to generate plasma discharges between the electrode 3 and a rotation body 30 and a guide circle plate 39 and a holder 42 that are electrically connected to this electrode, and a thin-film is formed on a work to be processed 7. At this time, while each holder 42 is moving in the circumferential direction within a reaction room 1a, it moves the same range in the radius direction, and a holder 42 revolves on its own axis. So each part on the work to be processed on the holder 42 moves the same range. This enables the degree of processing between each work to be processed 7 and within each work to be processed 7 to be uniform despite the difference of thin-film processing capabilities for the circumference and radius directions of the electrode 3.
